What is molecular mass?
Molecular mass is the sum of the atomic masses of all the atoms in a molecule. It is usually expressed in atomic mass units (amu) or grams per mole (g/mol). Molecular mass is used to determine the mass of a substance in chemical reactions and stoichiometry calculations.
How do you calculate the relative molecular mass of H2O WATER?

Why do relative molecular mass have decimals?
They are the calculated averages of all the isotopes of a particular element in accordance to their relative abundances, and hence is generally not an integer due to the mathematical division involved.
The relative molecular mass of water?
Water is composed of two hydrogen and an oxygen atom. Their respective atomic numbers are 1 and 16. Therefore the RMM of water is 2x1+16=18.
What is the relative molecular mass of methane?
Methane has four hydrogen atoms attached to a central carbon atom. Their atomic masses are 1 and 12 respectively. The RMM of methane is 4x1+12=16.

What is the symbol Mr used for in chemistry?
The symbol Mr in chemistry stands for the relative molecular mass of a compound. It represents the average mass of a molecule of the compound compared to one-twelfth of the mass of an atom of carbon-12.
Why do relative molecular mass have decimals?
They are the calculated averages of all the isotopes of a particular element in accordance to their relative abundances, and hence is generally not an integer due to the mathematical division involved.
How do you convert from molecular mass to grams per mole?
Relative molecular mass is obtained by summing up the atomic masses of atoms in the formula. The gram molecular mass denotes the mass of a mole of the substance in grams. Both of them are same in number.
What is the mass of CaCO3?
Molar mass of CaCO3 = 100.0869 g/mol
What the molecular mass of MgF2?
The Atomic Mass of Mg is 24. The atomic mass of fluorine is 19. Therefore the relative mass of the substance is 62.
What is the relative mass of so2?
The relative atomic mass of sulfur is 32.06 g/mol and the relative atomic mass of oxygen is 16.00 g/mol. Therefore, the relative molecular mass of SO2 (sulfur dioxide) is 32.06 + (16.00 x 2) = 64.06 g/mol.
What is the molecular equation of calcium carbonate?
CaCO3
What is the relationship between molecular mass and vapour density?
The relationship between molecular mass and vapor density is that they are proportional to each other. Vapor density is defined as the mass of a vapor relative to the mass of an equal volume of air, while molecular mass is the mass of a molecule of a substance. Therefore, a higher molecular mass will result in a higher vapor density.
What is the molecular formula for antacids?
The molecular formula for a Antacide could be NaHCO3 or CaCO3.
Molecular Formula for Calcium Carbonate?
The molecular formula for calcium carbonate is CaCO3. It consists of one calcium atom, one carbon atom, and three oxygen atoms.
